To aZZwLom t mag/concern:

Beitknown that we, EDWARD ALBREOHT and VALTER H. ScnUssLnR, citizens of the United States, yresiding in the city and county of Philadelphia, State of Pennsylvania, have invented a new and 'useful Hoisting and Dumping Vehicle, of which the following is a specification.

'Our invention comprehends a novel construction and arrangement of a hoisting and dumping vehicle wherein we eliminate the necessity of having working parts eX tending below the chassis or running gear of the vehicle, and wherein the number of parts employed is reduced t0 av minimum.

It further comprehends a novel vehicle body of the character stated, and novel actuating means for it, said body having its center of gravity the same when in raised position as itis when in lowered position.

It further comprehends a novel vehicle body and novel means for raising and lowering it.

Gther novel features of construction and advantage will hereinafter more clearly apreliable results, although it is to bek under-V stood that the various instrumentalities of which our invention consists can be variously arranged and that Aour invention is not limited to the precise arrangement and organization of these instrumentalities as Vherein shown and described.

v Figure 1 represents in side elevation a vehicle of the motor driven type, in conjunction with which af hoisting and dump-` ing rbody embodying our invention is employed.

.Fig 7 represents a section on line 7 7 o f Fig. 6. Fig. 8 representsin side elevationa portion of a side rail 3 seen in Fig. 6. `Similar numerals of reference indicate corresponding parts in the figures.

VReferring to the drawings.

1 designates a vehicle of any desired construction. IWe'have preferred to illustrate the vehicle as being of the motor driven type, but it is apparent that our invention can be employed in conjunction with any desired type of vehicle irrespective of the means employed to move it. The chassis or running gear 2 may be of any desired or conventional type and as shown is provided with side railsv 3 connected to it in any desired manner and which if desired may be apertured as at 4 in order to decrease the weight. The sides are slotted as at 5 to form a bearing'for anti-friction rollers 6 mounted at the ends of a shaft 7. The lower ends of lifting bars 8 are loosely mounted on the shaft 7 and their upper ends are pivotally connected at 9 to the frame 10 of the vehicle body 11 which latter may be of any desired construction. The bars 8 are braced by reinforcing strips 12 preferably connected with each other as at 13. The rear connected by cross braces 16 and cross bars 17. rllhe standards 15 are provided with spaced openings 18 to receive a stop rod 19 which has one end threaded vand provided with a nut to retain it in position. The lower ends of the standard are connected byV a rod 2O which carries a pulley 21, and a similar rod 22 is provided at the upperend which carries a pulley 23. 2er designates a cable which hasv one end fixed yto a pulley 25 fast on a winding shaft 26 journaled in the side rails 3. The shaft 26 is provided with a gear 27 which meshes with a pinion 28, fixed to a gear 29,\suitably mounted and meshing with a pinion 30 on a shaft 31 adapted to be revolved either byhand Vor mechanically, and as shown its' outer end -is shaped to receive a suitable handle 38.

The shaft 31 has fixed toit a ratchet -32 with which cooperates a pawl 33 to prevent the unwinding of the winding shaft. The cable passes from the pulley 25 rearfixed to the frame which carries the vehicle body.

The frame 10 at its forward end is provided with the anti-friction rollers 35 which are guided in the channel bars 15.

In the embodiment seen in Figs. 6 and 7, the construction is the equivalent of that shown in the other figures. The standards 15 curve rearwardly at their upper ends and the side rails 3 at their rear ends are provided with recesses 36 to receive the rear 'rollers carried by the body, and thus form a pivotal point for the upward movement of the forward end Iof the body. Arms 37 depend from the body to prevent lateral movement of it.

In the operation, it will be seen that when the winding shaft is revolved the front end of the body is elevated until it strikes the stop rod and then the pull on the cable moves the shaft 7 forwardly, thereby causing the bars 8 to raise the rear portion of the body into an inclined or horizontal position` as desired.

It will be apparent that in accordance with our present invention the wagon body can bemade higher than is possible with the ordinary constructionY of hoisting and dumping body. This is of especial advantage since the wagon body can be raised to such height that the contents can be discharged directly into or received from a freight car, or any elevated container. The center of gravity of the body remains the same, that is, it has the same relation with respect to the chassis when the body is in raised position as it does when the body is in its lowered ornormal position. It will be seen that when the front end of the wagon body is being raised it is accurately guided due to the anti-friction rollers carried by it which move inthe channels of the standards 15. These standards and the manner in which the wagon body is connected with them makes a very rigid construction, and prevents shaking or lateral movement of the body when it is in its elevated position. The raising bars 8 are pivoted near the center of gravity of the body, and toward the front and when in their normal or collapsed condition, they do not extend below the chassis, the advantage of which is evident.

It will be seen that when the vehicle body is in its raised position the rollers at the lower end of the lifting bars are in rear of the center of gravity of the-body, so that whenv the vehicle body is lowered the rear nd of the body will always start t0 lower rst.

It will be apparent from the foregoing that in the present invention we have reduced to a minimum the number of parts which it is necessary to employ to effect the raising and lowering of the vehicle body, with consequent reduction in the amount of friction created by the moving parts.

It will be apparent that the power required to raise the load is constant at any position of the vehicle body, whichrenders it easier to adjust the vehicle body to any desired height.

It will now be apparent that we have devised a novel and useful hoisting and dumping vehicle which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while we have, in the present instance, shown and described preferred embodiments thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that they are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
